Say 'x' is the current number of instances of a channel running in a Qmgr. Can x be stored as a curdepth of a queue ?
If yes, how to link the queue and the channel , so that x determines the current number of channel instances running.
MQ7 and Aix is the OS |

If you mean "number of client channels", no and why would you want to?

If what you actually want is to have the same number of processing applications (which would all open client channels) running as there are messages currently on a queue then yes you can achieve this.
But you don't want to. Consider what would happen in your AIX machine if 5,000 messages are suddenly dropped onto the queue and 5,000 instances of the application (with 5,000 channel) suddenly opened. What would likely happen quite quickly?
Hint: the answer contains the words "out", "memory", "of", "crash", "server", "fired" & "you" but not in that order.

This is a very strange suggestion. What is your design requirement? There is probably a way of meeting the requirement using normal MQ design patterns.
